LI Solutions for Fixed Network Operators

Utimaco LIMS enables fixed network operators to comply with national lawful interception requirements for both circuit-switched and packet-switched networks.

Broadband Access Interception

When it comes to monitoring Internet access networks, there is generally a choice between active and passive interception methods. With active interception, available network nodes, like routers and AAA servers, provide capabilities to monitor the authentication data as well as the IP media stream of persons under surveillance. Passive methods, however, rely on non-intrusive network probes that are integrated into the operator’s network to monitor all traffic. In some cases, a combination of active and passive methods provides the best results or is the only feasible solution.

Utimaco LIMS supports a large range of network routers and access gateways for virtually any type of broadband network. LIMS implements many vendor-specific interception methods, such as Cisco SII, Juniper DTCP, Nokia LIP, and many others.

Interception in Circuit-switched Networks

Voice interception in circuit-switched networks (e.g. ISDN, POTS) typically makes use of integrated interception capabilities of the telephone switches. Utimaco has implemented interfaces to telephone switches of all leading vendors, including Ericsson, Nokia Networks, Huawei, ZTE, and others.
